Determination of ofloxacin in the presence of dopamine, paracetamol, and caffeine using a glassy carbon electrode based on carbon nanomaterials and gold nanoparticles.

A new electrode was prepared based on functionalized graphene and gold nanoparticles dispersed in a chitosan film. Such an electrochemical sensor determines ofloxacin in the presence of dopamine, paracetamol, and caffeine. Characterization (morphological and electrochemical) was done using scanning electron microscopy, electrochemical impedance spectroscopy, and cyclic voltammetry.
